Definitions

  • This invention relates to vehicle doors, lift gates and other closures equipped with moveable windows and more particularly to a window regulator mechanism that is housed within the vehicle door, lift gate or other closure for raising and lowering the window.
  • Automotive vehicles have doors, lift gates and other closures that are commonly equipped with a window.
  • the window is moveable to provide an open passage between the vehicle interior and the vehicle exterior.
  • Moveable windows often slide up and down between a raised closed position and a lowered open position where the window is at least partially stored in the vehicle door, lift gate or other closure.
  • window regulator mechanisms are now used to raise and lower the window.
  • Known mechanisms include cross arm mechanisms, single arm mechanisms, cable mechanisms and tape mechanisms.
  • U.S. Patent 4,672,771 granted to Michael K. Lam et al on June 16, 1987 and U.S. Patent 4,839,990 granted to Michael K. Lam et al on June 20, 1989 disclose typical tape drive mechanisms.
  • the typical tape drive mechanism generally comprises a flat plastic drive tape that is fitted around a sprocket wheel and the tape has spaced transverse apertures or other conformations that cooperate with the sprocket wheel to drive the tape.
  • the tape is often routed through tape channels that follow the curvature of the windows. These curved tape channels edge bend the tape resulting in high frictional resistance when the tape is pushed through the tape channel.
  • systems requiring curved tape channels are very inefficient because large drive motors or considerable manual effort is required to move the window in one direction, usually down.
  • an object of the invention is to provide a window regulator mechanism of the tape drive type wherein the tape drive pulls the window in both directions resulting in a tape that is inherently more flexible and thus easier to route than tapes used in the past that were required to push the window in one direction and thus carry compressive loads.
  • a feature of the invention is that the window regulator mechanism has a tape that pulls the window in both directions thereby allowing the use of a more flexible tape that is easier to route inside the vehicle door, lift gate or other closure.
  • window regulator mechanism uses a flexible tape that is twisted so that it travels part way with its width parallel to the length of the vehicle door, lift gate or other closure.
  • window regulator mechanism does not require any tape channels thereby reducing the power or manual effort required to operate the window regulator mechanism.
  • an object of the invention is to provide a window regulator mechanism of the tape drive type that requires very little space in the sill area of the vehicle door, lift gate or other closure resulting in greater design freedom.
  • a feature of the invention is that the window regulator uses a tape in the form of a very thin flexible web that results in a mechanism that requires very little space in the sill area of the vehicle door, lift gate or other closure thereby providing considerable design freedom and/or increasing the permissible window height.
  • vehicle 10 has a door or closure 12 that is attached to the forward pillar of the vehicle by two hinge assemblies (not shown) so that the door swings from a closed position to an open position providing an open passage for entering and exiting the interior passenger compartment of the vehicle.
  • Closure 12 is equipped with a window 16 that slides up and down in a window frame 13 between a raised closed position and a lowered open position where the window is stored in the vehicle closure 12 as shown in dashed line in figure 1.
  • Window 16 is moved by a window regulator mechanism indicated generally at 18.
  • Window regulator mechanism 18 comprises a base plate 20 that is disposed in a space between inner and outer panels of closure 12.
  • Base plate 20 is secured to the inner panel by brackets 22 (figure 7).
  • Base plate 20 has an upper roller assembly 24 at the upper end (figures 3 and 4) and a lower roller assembly 26 at the lower end (figures 5 and 6).
  • a tape 28 wraps around rollers 25 and 27 of the respective upper and lower roller assemblies 24 and 26.
  • the tape 28 extends from the upper roller assembly 24 to the lower roller assembly 26 and lies substantially flat against the surface of base plate 20 facing the exterior side of closure 12 as best shown in figure 8.
  • Tape 28 is attached to window sash plate 30 between rollers 25 and 27 on the exterior side of base plate 20 as more fully explained below.
  • Window sash plate 30 is attached to the bottom of window 16 and is moved up and down with respect to base plate 30 by tape 28.
  • Window regulator mechanism 18 includes a reversible electric motor 32 and two tape drums 34 and 36 that are mounted on the interior side of base plate 20 near the middle of the closure 12 which is generally the widest part of the door.
  • Base plate 20 is preferably curved to follow the outer panel of closure 12 and thus maximize the space available for these regulator parts.
  • Tape drums 34 and 36 rotate on spaced parallel axes that are generally perpendicular to base plate 20.
  • Motor 32 drives tape drum 34 through a gear reduction set (not shown).
  • Drum 34 drives drum 36 in an opposite direction through meshing spur gears 38, 40 that are attached to the respective drums.
  • Tape 28 is attached to drum 36 at one end and then winds around drum 36, then exits drum 36, twists 90° and then wraps around roller 25 of upper roller assembly 24.
  • tape 28 then lies substantially flat against the exterior surface of base plate 30 from the upper roller assembly 24 to the lower roller assembly 26.
  • Tape 28 then wraps around roller 27 of lower roller assembly 26 and extends upwardly toward tape drum 34 on the interior side of base plate 20.
  • Tape 28 twists 90° after wrapping around lower roller 27 and winds onto tape drum 34 with the opposite end of tape 28 being attached to tape drum 34.
  • the number of times that tape 28 wraps around drums 34 and 36 depends on the position of window 16 with the total wrap of tape 28 on drums 34 and 36 being substantially equal to the required travel of window 16. In any event, enough tape is stored on drums 34 and/or 36 to move window 16 up and down between a raised fully closed position and a lowered fully stored position in closure 12.
  • Window 16 is raised and lowered by energizing reversible electric motor 32 through suitable electric controls that are well known in the art. Basically window 16 is lowered by energizing motor 32 so that tape drum 34 is driven clockwise as shown in figure 8. This winds additional tape onto drum 34 on the interior side of base plate 26 which pulls tape 28 down on the exterior side of base plate 20. As tape 28 is pulled down, window sash plate 30 and window 16 are pulled down with it. As indicated above tape drum 36 is simultaneously driven in the counterclockwise direction unwinding tape 28 at the opposite end.
  • window 16 is raised by energizing motor 32 to drive drum 34 counterclockwise and drum 36 clockwise.
  • tape 28 is wound on drum 36 at one end and simultaneously unwound from drum 34 at the other end. This pulls tape 28 up on the exterior side of base plate 20 raising sash plate 30 and window 16 to the closed position
  • tape 28 is always pulled to open or close window 16. Since tape 28 is not required to push window 16 in either direction, tape 28 can be made very thin and flexible and easy to route inside closure 12. Since tape 28 is very thin and flexible, tape 28 can also be wrapped around small rollers 25 and 27 at the upper and lower ends of base plate 20. For example, rollers 25 and 27 can be made approximately 0.375 inches (9.5 cm) in diameter. This results in a thin roller 25 and roller assembly 24 at the top of base plate 20 and allows locating upper roller assembly 24 very high in a thin sill area of closure 12 as shown schematically in figure 7. This feature provides considerable design freedom for closure 12 and increases the permissible height of window 16 which must be stored in closure 12.
  • Tape 28 is preferably a woven web of high tensile strength synthetic plastic material, such as nylon or polyester as is commonly used in seat belts. A tape 1 ⁇ 2 to 3 ⁇ 4 inches wide and 0.040 of an inch in thickness is sufficient for most automotive applications.
  • window regulator mechanism 18 preferably includes a slack-take up device 40 to avoid window drop when the window is lowered partially.
  • Slack take-up device 40 comprises splitting tape 28 to form ends 42 and 44.
  • Lower end 42 is anchored to window sash plate 30 securely.
  • Upper end 44 is attached so that it moves vertically with respect to window sash plate 30 under the bias of compression spring 46.
  • the upper end of compression spring 46 engages anchor tabs 48 of window sash plate 30.
  • the lower end of compression spring 46 engages a slide 50 that is attached to the upper end 44 of tape 28 below stop tabs 52 of window sash plate 30. Slide 50 engages stop tabs 52 when window 16 is in the full down position and tape drum 34 is full of tape 28.
  • drum 34 which contains several layers of tape 28 is driven counterclockwise. This drives drum 36 clockwise winding tape 28 onto drum 36 and pulling slide 50 up. Slide 50 being in engagement with stop tabs 52 pulls window 16 until window 16 is closed.
  • slack is initially produced in tape 28 and then taken-up in the portion of tape 28 between drum 34 and end 42. However, this does not effect the operation because the window is pulled up by the portion of tape 28 between slide 50 and drum 36 which remains taut due to the weight of window 16 and sash plate 30 and the fact that the force of compression spring 46 exceeds the weight of these components. Consequently the window raising operation can be stopped at any time and a partially open window 16 will not drop.
  • drum 34 is driven clockwise. This drives drum 36 counterclockwise and winds several layers of tape 28 off of drum 36 and onto drum 34 pulling slide 50 down.
  • slack which would normally build up between stop tabs 52 and drum 36 is taken up by expansion of compression spring 46 which moves slide 50 away from stop tabs 52.
  • slide 50 re-engages stop tabs 52 because more tape is being wound onto drum 34 than is wound off drum 36 during the latter stages of the operation.
  • the window lowering operation can be stopped at any time and the partially closed window 16 will not drop because any slack would be taken up by expansion of compression spring 46.
  • FIG. 9 An alternate slack take-up device 150 is shown in figures 9 and 10.
  • both tape ends 42 and 44 are anchored to window sash plate 50 securely; the drum portion 152 of tape drum 36 is separated from the gear portion 154; and a compression spring 156 is operatively interposed between the drum portion 152 and the gear portion 154.
  • Drum portion 152 includes a drive shoulder 153 while gear portion 154 includes a drive shoulder 158 and a stop tab 160.
  • Figures 11, 12 and 13 show an alternate window regulator mechanism 118 that also uses a tape 128 that pulls the window in both directions.
  • Window regulator mechanism 118 comprises a base plate 120 that is disposed in a space between inner and outer panels of a closure (not shown) and secured to the inner panel by brackets (not shown).
  • Base plate 120 has an upper roller assembly 124 at the upper end (figures 12 and 13) and a lower roller assembly 126 at the lower end.
  • An endless tape 128 wraps around rollers 125 and 127 of the upper and lower roller assemblies 124 and 126.
  • the tape 128 extends continuously from the upper roller assembly 124 to the lower roller assembly 126 and lies substantially flat against the surface of base plate 120 on the exterior side of the closure as best shown in figure 9.
  • Window sash plate 130 is attached to tape 128 on the exterior side of base plate 120 between rollers 125 and 126 and to the bottom of window 16.
  • Tape 128 can also be split to facilitate assembly. When split, the two ends of tape 128 are fastened to window sash plate 130 securely. Thus for all practical purposes tape 128 is an "endless" tape even when split for assembly purposes.
  • Window regulator mechanism 118 includes a reversible electric motor 132, a tape drum 134 and an idler drum 136 that are mounted on the interior side of base plate 120 near the middle of the closure which is generally the widest part of the closure.
  • Base plate 120 is preferably curved to follow the outer closure panel and thus maximize the space available for these regulator parts.
  • Tape drive drum 134 and idler drum 136 rotate on spaced parallel axes that are generally perpendicular to base plate 120.
  • Motor 132 drives tape drive drum 134 through a gear reduction set (not shown).
  • Endless tape 128 wraps around tape drive drum 134 in one direction and then wraps around idler drum 136 in an opposite direction. Tape 128 then twists 90° and wraps around roller 127 of lower roller assembly 126.
  • endless tape 128 then lies substantially flat against the exterior surface of base plate 130 from the lower roller assembly 126 to the upper roller assembly 124. Endless tape 128 then wraps around roller 125 of upper roller assembly 124 and then extends downwardly toward tape drive drum 134 on the interior side of base plate 120. Tape 128 twists 90° after wrapping around upper roller 125 then proceeds onto tape drive drum 134. Endless tape 128 has a series of equally spaced conformations, such as slots 137 that receive equally spaced conformations, such as radial teeth 138 on drive drum 134 when tape 128 is wrapped around drive drum 134. Conformations 137 and 138 cooperate to form a driving connection between endless tape 128 and tape drive 134. Other conformations may be used to perform this driving function.
  • Window 16 is raised and lowered by energizing reversible electric motor 132 through suitable electric controls that are well known in the art. Basically window 16 is lowered by energizing motor 132 so that tape drive drum 134 is driven counterclockwise as shown in figure 9. This pulls tape 128 down on the exterior side of base plate 120. As tape 128 is pulled down, window sash plate 130 and window 16 are pulled down with it. On the other hand, window 16 is raised by energizing motor 132 to drive drum 134 clockwise. This pulls tape 128 up on the exterior side of base plate 120 raising sash plate 130 and window 16 to the closed position.
  • tape 128 is always pulled to open or close window 16. Since tape 128 is not required to push window 16 in either direction, tape 128 can be relatively thin and flexible and easy to route inside the closure.
  • Window regulator mechanism 118 does not need a slack-take up device 40 or 150 because tape 128 is not wound onto one drum while being wound off another drum.
